Tibro Heating Plant, Sweden

Background:

The district heating plant in Tibro is owned by Nevel AB. Nevel AB currently operates over 40 district heating networks in Finland, Sweden, and Estonia. In Tibro, the plant consists of a biofuel boiler with local fuel from the Swedish forest. The installation of the ORC system promotes Nevel’s sustainability goals, which include investment in renewable energy and reduction of carbon dioxide emissions. With the investment in an ORC system, Nevel in Tibro gets its own supply of green fossil-free electricity that also supports the local electricity grid.

Our solution:
An automated ORC system with a maximum capacity of 99.9kW was supplied by Againity. The ORC system solution enables the production of electricity from the hot water of the biofuel boiler. In total, the system is expected to produce 560 MWh annually, which corresponds to 504 tonnes of CO2 equivalents when substituting coal-based electricity.

Tomelilla Heating Plant, Sweden

Background:

The district heating plant located in Tomelilla began its production in the 1980s at the industrial area. District heating was later extended to the urban area in 1999 and is currently owned by Solör Bioenergi Syd AB. There are two boilers at the Tomelilla heating plant, and the fuel consists mainly of residues from the forest industry. Solör Bioenergi has previously invested in ORC systems for Flen, Hörby, Svenljunga and Vilhelmina, among others. The addition of the ORC system is fully aligned with Solör Bioenergi’s goal to utilize the forest’s resources and create a sustainable society, supported by lower energy costs from the ORC system.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 99.9 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 430 MWh annually, corresponding to emission savings of 387 tonnes of CO2 equivalents when substituting coal-based electricity.

Againity’s first reference in Poland!

We are thrilled to announce that we will deliver two 200 kW ORC turbines for clean electricity production at Kozienice heating plant in Poland. Special thanks to our sales partner NPS New Power Sources Sp. z o.o., this would not have been possible without your contribution. Thanks also to Energika Zbigniew Szamałek Sp. K. for a great collaboration so far. This project not only enhances energy efficiency but also contributes to a more sustainable future with climate-smart baseload power. Together we create a more sustainable European electricity system!

Study visit at Ystad Energi

Last week, the Againity team had the privilege of hosting a study visit at Ystad Energi AB’s heating plant. There were a total of 60 participants, with 40 of them on-site while the rest joined us virtually.
 
During our visit, all participants had the opportunity to gain a deeper understanding of how the ORC operates and also listen to our customers’ experience and insights on how they now are mostly self-sufficiency in fossil-free electricity.
 
Thank you to all of you who participated in the event. Together, we can make a difference in the energy transition, producing more plannable electricity!

Flen heating plant, Sweden

Background:

The district heating production in Flen started in the early 2000s and is operated by Solör Bioenergi Fjärrvärme AB. The plant consists of two biofuel boilers where mainly sawdust, wood chips and bark from the local area are burned. Solör Bioenergi aims to take advantage of the forest’s resources and contribute to a sustainable society with reduced carbon dioxide emissions, which together with reduced energy costs has justified an investment in an ORC turbine. Solör Bioenergi has previously invested in ORC turbines for the heating plants in Hörby, Svenljunga and Vilhelmina.

Our solution:
Againity delivered an automated ORC system with a maximum capacity of 99,9 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 519 MWh electricity annually, corresponding to annual emission savings of 467 tonnes of CO2 equivalents when substituting coal-based electricity.
